4 Series Mixed Signal Oscilloscopes

Tektronix 4 Series MSO

With a remarkably innovative pinch-swipe-zoom touchscreen user interface, a high-definition display, and 4 or 6 FlexChannel® inputs that let you measure one analog or eight digital signals per channel, the 4 Series MSO is ready for today’s toughest challenges, and tomorrow’s too. It sets a new standard for performance, analysis, and overall user experience.

Never let a lack of channels slow down your verification and debug process again!

 

The 4 Series MSO offers better visibility into complex systems by
offering four and six channel models with a 13.3-inch high-definition
(1,920 x 1,080) display. Many applications, such as embedded
systems, three-phase power electronics, automotive electronics, power supply design, and DC-to-DC power converters, require the observation of more than four analog signals to verify and characterize device performance, and to debug challenging system issues.


Most engineers can recall situations in which they were debugging a
particularly difficult problem and wanted greater system visibility and context, but the scope they were using was limited to two or four analog channels. Using a second scope involves significant effort to align trigger points, difficulty in determining timing relationships across the two displays, and documentation challenges.


And while you might assume that a six channel scope would cost 50% more than a four-channel scope, you'll be pleasantly surprised to find that six channel models are only ~20% more than four channel models.


The additional analog channels can pay for themselves quickly by
enabling you to keep current and future projects on schedule.

 

FlexChannel® technology enables maximum flexibility and broader system visibility

The 4 Series MSO redefines what a Mixed Signal Oscilloscope (MSO) should be. FlexChannel technology enables each channel input to be used as a single analog channel, eight digital logic inputs (with the TLP058 logic probe), or simultaneous analog and spectrum views with independent acquisition controls for each domain. Imagine the flexibility and configurability this provides.


With a six FlexChannel model, you can configure the instrument to look at six analog and zero digital signals. Or five analog and eight digital. Or four analog and 16 digital, three analog and 24 digital and so on. You can change the configuration at any time by simply adding or removing TLP058 logic probes, so you always have the right number of digital channels.

 

Previous-generation MSOs required tradeoffs, with digital channels
having lower sample rates or shorter record lengths than analog
channels. The 4 Series MSO offers a new level of integration of digital channels. Digital channels share the same high sample rate (up to 6.25 GS/s), and long record length (up to 62.5 M points) as analog channels.

 

Unprecedented signal viewing capability

The stunning 13.3-inch (338 mm) display in the 4 Series MSO is the
largest display in its class It is also the highest resolution display, with full HD resolution (1,920 x 1,080), enabling you to see many signals at once with ample room for critical readouts and analysis.

 

The viewing area is optimized to ensure that the maximum vertical
space is available for waveforms. The Results Bar on the right can be
hidden, enabling the waveform view to use the full width of the display.

 

The 4 Series MSO offers a revolutionary new Stacked display mode. Historically, scopes have overlaid all waveforms in the same graticule, forcing difficult tradeoffs:

  • To make each waveform visible, you vertically scale and positioneach waveform so that they don't overlap. Each waveform uses asmall percentage of the available ADC range, leading to lessaccurate measurements.
  • For measurement accuracy, you vertically scale and position eachwaveform to cover the entire display. The waveforms overlap eachother, making it hard to distinguish signal details on individualwaveforms

 

The new Stacked display eliminates this tradeoff. It automatically addsand removes additional horizontal waveform 'slices' (additional graticules) as waveforms are created and removed. Each slicerepresents the full ADC range for the waveform. All waveforms are visually separated from each other while still using the full ADC range,enabling maximum visibility and accuracy. And it's all done automatically as waveforms are added or removed! Channels caneasily be reordered in stacked display mode by dragging and dropping the channel and waveform badges in the Settings bar at the bottom of the display. Groups of channels can also be overlaid within a slice to simplify visual comparison of signals.

 

The large display in the 4 Series MSO also provides plenty of viewingarea not only for signals, but also for plots, measurement results tables,bus decode tables and more. You can easily resize and relocate thevarious views to suit your application.
